When people said Africa would change me, I didn't understand what they meant. To see the poverty in the townships, for instance, is overwhelming. I found it heart-wrenching to see young children walking barefoot and hungry in the dirt. I'm the kind of person who wants to change the world right here and now, so I got frustrated.

Cynicism masquerades as wisdom, but it is the furthest thing from it. Because cynics don't learn anything. Because cynicism is a self-imposed blindness: a rejection of the world because we are afraid it will hurt us or disappoint us. Cynics always say 'no.' But saying 'yes' begins things. Saying 'yes' is how things grow.
